for sealing of impermeable joints

If the expansion joint is to be additionally sealed, a rubber water bar cage is integrated into the Stremaform® formwork elements during production. The expansion rubber water bar is inserted into the cage at the building site. The built-in expansion joint fixer ensures the correct position of the rubber water bar.

For wide rubber water bars, we recommend a formwork element design in which the rubber water bar is rolled out on the lower part before the upper part is positioned and secured.

for the acoustic separation of concrete components

The Stremaform® elements for sound insulation are used for acoustic decoupling of concrete components. In semi-detached and terraced houses, this avoids the transmission of sound between neighbouring homes.

A rubber water bar cage can be integrated into the element to seal the sound insulation joint. The expansion joint tape is inserted into the cage on building site.

for sealing and load transmission

The Stremaform® formwork element in combination with Egcodubel or Egcodorn and rubber water bar cage is an efficient solution for expansion joints which guarantees shear force transmission and sealing. The integrated rubber water bar cage and the already installed shear force dowel accelerate installation on the building site.

The following products can be integrated for shear force transmission:

Max Frank recommends

Expansion joints in concrete structures are particularly complex and cumbersome, from the design and planning stage all way to execution in the field. Whenever the transmission of transverse/shear forces in combination with structural waterproofing is required, the task becomes even more daunting.
